    Three lines on a chart
    1. __________ __________ Calculate the velocity (speed) for the first table (the lowest line).
    2. __________ __________ Calculate the velocity (speed) for the second table (the middle line).
    3. __________ __________ Calculate the velocity (speed) for the third table (the top line).

  6. A marble with a mass of 5.0 grams is 20 centimeters above a table on an orange plastic track. The marble is released and rolls down the ramp onto the table. Use an acceleration of gravity g equal to 980 cm/s² for this question.
    1. __________ __________ Calculate the Gravitational Potential Energy of the marble before the marble is released using the formula GPE = mgh.
    2. __________ __________ The kinetic energy at the bottom of the ramp should be equal to the GPE the marble had at the top of the ramp. Solving Kinetic Energy KE = ½mѵ² for ѵ, calculate the velocity that the marble should have at the bottom of the ramp.
    3. __________ In the laboratory using an actual marble and the orange track, will the marble have the speed you just calculated?
    4. __________ Will the actual marble speed be faster OR slower than you have calculated?
